Was only in the section for about 2 years and from memory there were quite a few blocks that couldn't be used, besides the ones in reserve for QEA (NSW), TAA and Ansett/ANA (Vic/Tas) as well as the aero clubs etc,. The Department looked after their own with the VH-CAx block.

If it were run by the Roads and Maritime Board, they would charge a large yearly fee for a registration number out of sequence. Do you want it in a different colour? Add another yearly fee. Just my little dig.

And is there an example to follow with Ireland adding EJ-xxxx to the current EI-xxx ?

Probably not. VH is for aircraft reg, the adjoining VI prefixnisnused by radio licencing. If anything I would suggest 4 letters, as the ACMA has done for the Amateur Radio VK suffixes. We have 2, 3 and now 4 letter suffixes in that range.
